Abstract: In various embodiments, methods, systems, and vehicles are provided for masking a tonal noise of a motor. In certain embodiments, a vehicle includes a drive system and an active masking acoustic signal generator (AMAG). The drive system includes a motor generating a tonal noise. The AMAG is configured to at least facilitate masking the tonal noise, by introducing a complementary harmonic tone, injecting dithering into the motor, or both.

Abstract: A method of masking sounds associated with a vehicle is provided. The method includes performing on processing circuitry, monitoring of vehicle data. A tonal disturbance type and a tone to mask associated with the tonal disturbance type are identified based on the vehicle data. A shaped band of sounds is determined based on the tone to mask. The shaped band of sounds covers a range of frequencies around the tone to mask. The shaped band of sounds is applied to an audio output of the vehicle.

Abstract: A method of controlling a power inverter coupled to an electric motor in a vehicle powertrain having an engine is provided. The method includes generating a voltage waveform signal and a switching frequency signal for the inverter via a controller. At least one of the voltage waveform signal and the switching frequency signal is at least partially based on at least one commanded engine operating parameter. For example, the engine on/off state, engine torque, and engine speed can be considered. A vehicle having a controller configured to implement the method is also provided.

Abstract: A vehicle including a powertrain system that includes an electric machine electrically connected to a power inverter is described, wherein the powertrain system is operative in an electric vehicle mode to generate propulsion torque. A method for controlling the powertrain system includes determining a vehicle speed, and determining a preferred audible sound to be generated by the powertrain system when operating in the electric vehicle mode at the vehicle speed. A control signal for the power inverter is determined, and is associated with operating the powertrain system in the electric vehicle mode at the vehicle speed. The preferred audible sound is incorporated into the control signal for the power inverter, and the power inverter is controlled to operate the electric machine employing the control signal and the preferred audible sound.
